Yes? You mention it too - parents glued to their phones, part of the problem. Kids seeing their parents reading a book vs being glued to their phones really isn't the same thing, far from it. They can come and see pages of printed text in a book, vs some endless tiktok/instagram feeds of shallow video entertainment. Guess which they will stay around and stare endlessly without even blinking.

Screens and especially active content are incredibly addictive and small kids have no way of being rational and throttle their use. If they see the same behavior in their parents that's it.

Its not about having stay-at-home parent, but about spending the time with kids to be 100% physically there for them and them only, no running screen of any type anywhere in sight. Lets be honest, this is a rather rare sight.
